What is the navigation drawer icons size?

Question

I need to know the correct size (artboard and content) for Navigation Drawer icons.

It doesn't say anything on the Navigation Drawer specs: http://www.google.com.br/design/spec/patterns/navigation-drawer.html#navigation-drawer-specs

Thanks!

If you only need the icon size to set the dimensions of a view component you can use the Toolbar.Button.Navigation style. Here is an example where I create a fake navigation icon view.

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/vCoordinatorLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <!--CONTENT VIEW-->
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

        </LinearLayout>

        <!--FAKE TOOLBAR NAVIGATION ICON-->
        <RelativeLayout
            android:layout_width="?attr/actionBarSize"
            android:layout_height="?attr/actionBarSize">
            <ImageView
                android:id="@+id/vToolbarNavigationIcon"
                style="@style/Widget.AppCompat.Toolbar.Button.Navigation"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerInParent="true"
                android:src="@drawable/my_icon"/>
        </RelativeLayout>

    </android.support.design.widget.CoordinatorLayout>

You can check the official implementation of NavigationView provided by the support design library.

If you see the code of NavigationMenuItemView it defines:

this.mIconSize = 
 context.getResources().getDimensionPixelSize(dimen.navigation_icon_size);

where:

<dimen name="navigation_icon_size">24dp</dimen

Answer 3

I would vote up Balar's answer, but it is off by one small detail. The correct answer is that all small icons should be 24 x 24 dp.

Answer 4

For:

mdpi : 24 x 24 px
hdpi : 36 x 36 px
xhdpi : 48 x 48 px
xxhdpi : 72 x 72 px
xxxhdpi : 96 x 96 px

According to their ratios:

mdpi : hdpi : xhdpi : xxhdpi : xxxhdpi= 1 : 1.5 : 2 : 3 : 4

Update:

Now google published Material icon design with more details.icons may be scaled down to 20dp with a trim area of 2dp surrounding the icon.
